Description

Check basic operation of $loadIdx:
  - A: load the data and each index set all via $loadIdx
  - B: load the data and index sets, assuming common index sets
  - C: load the data and index sets, using aliases for common sets
  - D: load just the data, index sets pre-loaded
  - E: load just the data, index sets pre-loaded, use some aliases
